6 Ways to Have a More Sustainable Halloween

All the fun, a fraction of the waste.

Halloween is one of the most beloved holidays of the year — and one of the most wasteful. Between single-use costumes, mountains of candy wrappers, plastic decorations that last one season, and the sheer volume of stuff purchased and discarded in a matter of weeks, the environmental footprint of October 31st is bigger than most people realize.

The good news: a sustainable Halloween doesn't mean a boring one. It means being a little more intentional about where things come from, how long they last, and what happens to them when the holiday is over. Here's how.

1. Buy, Borrow, or DIY Your Costume

Fast fashion Halloween costumes are among the most wasteful purchases of the year. Most are made from cheap synthetic materials, worn once, and thrown away — with no realistic path to recycling or donation given their novelty nature. An estimated 7 million costumes end up in UK landfills alone each year, and the numbers in the US are similarly staggering.

Better options exist at every budget:

• Shop secondhand first — thrift stores go into full Halloween mode in October and are stocked with costume pieces, accessories, and full outfits at a fraction of the price of new
• Borrow from friends and family — a group text asking if anyone has pieces you can use is free and often surprisingly productive
• Build from what you own — the most creative costumes are often assembled from real clothing you'll actually wear again after Halloween
• Rent a costume — costume rental shops offer high-quality options without the ownership footprint
• If you buy new, buy quality — a well-made costume stored properly can be worn for years, loaned out, or donated after the fact

The goal is simple: keep it out of the trash on November 1st.

2. Choose Reusable or Natural Decorations

Halloween decor has a plastic problem. Most of what fills the seasonal aisles is made from virgin plastic designed to last one season and then head to landfill — it's not recyclable, it's not durable, and it's not worth the footprint.

Sustainable alternatives that still deliver on atmosphere:

• Pumpkins and gourds — the original Halloween decoration, fully compostable after the season
• Dried corn stalks, hay bales, and autumn leaves — natural, seasonal, and beautiful
• Beeswax or soy candles in reusable holders instead of plastic LED decorations
• Vintage and secondhand decor from thrift stores, estate sales, and online resale — often more interesting and higher quality than new
• Invest in quality pieces you'll use year after year — a well-made ceramic skull or cast iron lantern beats a plastic skeleton every time

Carve pumpkins, roast the seeds, and compost the shells when you're done. Zero waste, full Halloween energy.

3. Rethink the Candy

Candy is the heart of Halloween and the source of one of its biggest waste streams — individually wrapped candy generates an enormous amount of single-use plastic and foil packaging that cannot be recycled through standard curbside programs.

A few ways to reduce the candy footprint without being the house that gives out raisins:

• Buy in bulk when possible to reduce outer packaging
• Choose candy brands with more responsible packaging — some companies are moving toward compostable or recyclable wrappers
• Offer non-candy alternatives for trick-or-treaters — stickers, temporary tattoos, small toys, and coins are genuinely appreciated and generate no food waste
• Buy only what you'll realistically distribute to avoid leftover candy waste
• Support candy companies with ethical sourcing — Halloween is one of the biggest chocolate consumption moments of the year, and conventional chocolate supply chains have well-documented labor and environmental issues; Fair Trade and direct-trade options exist

4. Use Natural Halloween Makeup

Halloween makeup is a category where non-toxic really matters — especially for kids. Conventional face paint and costume cosmetics often contain synthetic dyes, heavy metals, and skin irritants, applied directly to the face and sometimes left on for hours.

Look for:

• EWG Verified or Made Safe certified face paints for kids
• Natural pigments and mineral-based makeup for adult costumes
• Brands with full ingredient disclosure — if the ingredients aren't listed, keep looking
• Coconut oil or shea butter for removal instead of makeup wipes, which are single-use and largely non-recyclable

Your skin — and your kids' skin — is your largest organ. What goes on it matters, even for one night.

5. Make Halloween Treats from Scratch

For parties, school events, or home celebrating, homemade treats are a genuinely better option than individually packaged ones — less packaging, better ingredients, and usually more delicious. Halloween baking doesn't have to be elaborate: pumpkin muffins, spiced apple cider, decorated sugar cookies, and caramel apples are all simple, crowd-pleasing, and fully customizable.

Using seasonal ingredients — real pumpkin, apples from a local orchard, fresh spices — connects the celebration to what's actually happening in the natural world in October, which is what the holiday is rooted in.

6. Plan for What Comes After

The most sustainable part of Halloween is what you do on November 1st.

• Compost your pumpkins — most municipal composting programs accept them; some cities even hold pumpkin drop-off events after Halloween
• Donate unworn or gently used costume pieces to thrift stores, theater programs, or community costume swaps
• Store quality decorations carefully so they last another year
• Collect and properly dispose of candy wrappers — TerraCycle runs a candy wrapper recycling program that accepts what curbside won't

The holiday lasts one night. What you do with everything it generates lasts a lot longer.

Halloween Without the Hangover

A sustainable Halloween isn't a lesser Halloween. It's one where the fun is intentional, the waste is minimal, and the choices you make reflect what you actually value — not just what's easiest to grab off a shelf in October.

Costume, candy, decorations, cleanup. Think it through once, and the whole thing gets easier every year.
